From what I have seen the top 3 are the Jr. Ducks 3, Gold Rush 1 and Jr. Kings 1. Haven't seen anyone in San Diego.
Top 2 are very clear:
(1) JR Ducks 3 -- to best of my knowledge, still undefeated
(2) Goldrush 1 -- won all games except against Jr Ducks 3.
Also good games (but not as consistent) coming from Kings 1, Bears, Mariners, Goldrush 2, Ducks 1, and SDIA
Of course, it's mites, so no scores are kept ... pizza and participation trophies for everyone.
